It's not like Detroit is Denver. Detroit affects us all and I'm not out in Waterford or Northville. I'm as close to Detroit as anyone outside the city. In fact our fire department puts out fires in Detroit because Detroit is so pathetic.
So if you want to make a new sub "Detroit-for-blacks-residents-only" feel free. It's easy to create a sub. Last I checked the city of Detroit used to be mostly whites. Most of the houses in Detroit at one time had a white person living in them.
So it's not like blacks have some claim to Detroit that white suburbanites have to keep their hands off.
People in the burbs have as much interest in Detroit as those that live there. Deal with it.
